I am using the Sprint HTC Hero. I absolutely love the screen. I recently converted my kid from the iphone (Hallelujah!) and he is now selling his iphone to get the Hero. Is there a way to get FULL SCREEN caller ID for incomming calls? If not full screen, how about larger pics. I've experimented with using larger and smaller pics, but they always come out the same. Sorry if this has been asked before.
